Engine surging
I have a 1993 gxe and everytime i put it in park it surges (goes up to 2k rpm then drops on its face repeatedly) sometimes it only does it once or twice but other times it keeps doing it until i put it in drive then it drops on its face again and its fine after that i recently cleaned the upper and lower intake, egr valve, and throttle body, and replaced fuel injectors and air filter and fuel filter to try to fix it but nothing has helped

it only does it when in park any other time it is fine i could be at a stop light and it would be fine but if i put it in park it starts surging
